Base64 Encode
Base64 packs arbitrary bytes into a text-safe alphabet so they can travel through fields that expect plain text. This tool encodes your input to Base64 for use in off-chain payloads and memos. It runs entirely in your browser with no network call.
Type UTF-8 text to see its hex and Base64 encodings. To decode hex back to text, paste it below.

Why Base64 exists
Base64 represents three bytes with four ASCII characters, letting binary data pass through text-only channels such as JSON fields, data URIs and token metadata. In crypto tooling it commonly appears in off-chain payloads, signed message bodies, and metadata referenced by a transaction rather than stored inline in calldata.
Encoded output is larger
Base64 grows the data by roughly one third because four characters carry three bytes. That trade buys safe transport through text pipelines, which is why memos and metadata blobs are often Base64-encoded before being attached off-chain.
Sıkça sorulanlar
Is Base64 encryption?
No. Base64 is reversible encoding, not encryption. Anyone can decode it, so never use it to hide secrets.
Is my input sent to a server?
No. Encoding runs locally in the browser with no network request and no API key.
